Extended data:
The cultivation of rhododendron and matters needing attention are as follows:
1, basin soil
It is more suitable to use earthen pots, with holes in the bottom and good ventilation effect. Because rhododendron has shallow roots and slow growth, you can choose a smaller pot, which will not be wasted when watering and is more conducive to growth.
In terms of basin soil, acid soil with loose texture and good drainage should be selected, and some humus soil and sawdust can also be selected. When filling basin soil, pay attention to using coarse soil at the bottom and fine soil at the top. In terms of remediation of basin soil, newly planted soil can be changed once every two years or once every three to five years from 1 to 10.
water
Rhododendron root is very thin, and its absorption ability is poor, so water can only reach the flower body through root absorption. Therefore, in addition to the winter dormancy period, the rhododendrons should be watered frequently, especially in the growth period after March, flowering period and high temperature period from July to September every year.
It is best to ensure that it is watered twice a day, and it can be watered less in autumn and winter. It should be noted that the tap water for watering flowers should be stored in a vessel for a day or two before watering flowers.
3. Lighting equipment
In the process of rhododendron cultivation, we should always ensure sufficient light, because only with sufficient light can we produce good flowers. Of course, you can't be exposed to the sun in hot summer. Instead, it is necessary to strengthen the shading work to prevent it from being damaged by the sun. In addition, the flowering period should be properly protected, which can be protected by shading nets, and the flowering period should not be exposed to the sun.
Step 4 apply fertilizer
Proper fertilization can make rhododendron grow stronger and faster. Like most indoor flowers, the principle of fertilizing azaleas is to fertilize more, that is, put less at a time and apply more times.
Apply fertilizer two or three times when the old leaves turn green, during and after flowering, and never apply fertilizer when the weather is hot. Rhododendron cultivation and fertilization can use grass juice, fishy water, rapeseed cake and other materials. In addition, the weak branches should be cut off in time so as not to affect the healthy growth of other branches.
5, pest control
In the process of rhododendron cultivation, the main pests are bugs, aphids and so on. When pests are found, if the number is small and visible to the naked eye, they can be wiped off with a wet cloth. If the pests are serious and large, you should buy insecticidal liquid from the local pharmacy for effective control. Placing azalea flowerpots in a well-ventilated and well-lit place and in a dark place is also one of the causes of pests.
